Please Note: These lenses must be held several inches above the page to produce a magnified image. They do not magnify when placed directly on a surface. The level of magnification increases gradually as the lens is raised higher above the page. Maximum magnification occurs around ten inches from the surface. Therefore, they are not recommended for use with computer monitors or for reading music sheets, as the lens would need to be positioned a sufficient distance from the surface to work.
